Third, to provide a machine of ithiscla'ssiwhic'h incorporates a novelmeansjofworking the pow-1' V ,der or the like into the discharging end10f the machine so that the discharging end remains full of the powderuntil the bin or hopper there-i abouts has been completely'emptied; L

. Fourth, to provide amachine of this class which ,incorporates a novelmeanslwherebythe feeding mechanism may be set into operation orIrendered inoperative readily and-quickly as desired,-

hereinafter described in detail and particularly set forth in theappended claims, reference being had to the accompanying drawings and tothe characters of .reference thereon whichiorm a part of thisapplication in which; 1 i I 7 Figure 1 is a side elevational View of themarking machine with one wheel removed; Fig.':2.= is an enlargedfragmentary-transverse sectional View through 2-2 ofFig. 1; Fig. 3 isan'enlarged partial-sectional partial-plan View through 33 1 of Fig. 2;Fig. 4 is another enlarged sectional View through44ofFig.2.

Hopper 1..nojzzle Shell 2, brackets 3, shaft 1i,

depending, bracketsB which are provided with alined bearings 311 at.their lower. extremities adaptedtovreceive the shaft 4. The shaft .4 *extends through the nozzle shell 2 in concentric relation with;;its;:axis.'-The;extremities; ofthe shaft 4 are provided -with, wheels 5 which aresecured thereto wherebythe wheels and shaft turn asa .unit.f-,The lowerside of the nozzle shell 2 is provided with aslot 2a therein which isorconstant-width and extendsaxiall-y. i

Ant-impeller sleeve 7 .is mounted on the shaft 4: at the portionthereofextending through the. nozzle shell 2. i The sleeve 7 .protrudes'with the shaft through theends of the nozzlezshe'll 2. The portion'ofthelimpellersleeve within the nozzle shell 2isprovided with severalimpellers 8 which are the form of circular disks disposed inparallelzrelation with each other but in oblique relation withtheimpeller sleeve 7. As the impeller sleeve turns, the lower: portions ofthe several impellers oscillate laterally, that is, axially within thenozzle shell. 1 3 "The impeller sleeve .isxrevolubly mounted withrespectto the shafts andis heldgagainst axial movement relative theretoby means :of collars 7a disposedlwithin. the ends of the .nozzle shell2. At one. protruding end the impeller. sleeve is provided with a seriesof A axially extending slots 71) forming a clutch .element. The adjacentexposed portion'of the shaft 4 receivesz'a clutch sleeve 9 'whichisheld. inslideable relation there- ;with.by-means ofa pin and slotarrangement nel which receives a forked end 10a of a clutch lever:10.-The .clutch'lever 10 extends hackwardly from the shaft 4,. and isjournaled intermediate its ends from a supportingQbar v11. The support.bar 11 is substantially U-shaped and secured by its ends to .thebracket.3,iand dispos'edso as .to extend along the rear-lower side ofthe bin 1. The screen slot 2a of the nozzle'shellis adapted to'bec'ontrolledby'aregulator gate 12; Said gate'comprises' an arcuate gateportion 12c extendingaxially along and. fitting adjacent the bottomofthe nozzle shell 2.. The ends ofthe. gate :portion 12a are providedwith upturned arms 12b which journal on the impeller sleeve between thecollars "la and the ends of the nozzle The upp r side.

shell' 2.: :.7oumaled onrthe impeller sleeve 7 at the ieiidthereoffdpriosite from the clutch element 7b, is a regulator lever 13wh1ch extends downwardly therefrom forming a handle 13a at its lowerextremity. The corresponding end of,

the nozzle shell 2 is provided with an arcuate slot 21) therein adaptedat all times to be covered by the upper portion of the regulator lever13. A connecting screw 14 extends through the slot 2b so as to join thelever 13 with the corresponding arm 12b of the regulator gate 12, thusby,

shifting the lever arcuately, the exposed portion of the slot 2a may bevaried.

The nozzle shell 2 is provided with a nozzle 15 which'has an upperportion that conforms to the lower portion of a nozzle shell andconnected thereto at one side by means of a hinge 16 and at the oppositeside by means of a clip 17, as shown best in Fig. 4 The lower end of thenozzle l5 converges to a rectangular opening of the desired width andlength. The upper portion of the nozzle 15 carries a screen 6 which isadapted to conform to and fit againstithe lowerside of the nozzle shell2 so as to cover the slot 2a.

1 Disposed on the forward and back-sidesrespectively of the converginglower portions lb of the bin l are a pair'of shakerplates 18; Eachshaker plate is substantially triangular with an apex pointingdownwardly. This apex is provided with a forked portion 18a which isadapted to straddle the central impeller 8 so that as the periphery ofthe impeller moves back and forth, the lower end-of the shaker plate isshifted like: wise. Each shaker plate '18 is journaled intermediate its'upper end on a pin 181) so that the plateoscillates about said pin asits lower end is shifted laterally. The plates 18 occupy approximatelythe entire rear and forward ends of the converging portion lb, thus vmovement .of the impeller causes the shaker plate to work the powder orother materialin the bin towards'the nozzle shell 2.

The lateral sides of the hopper 1 are provided with handlebars 19 whichextend upwardly and backwardly to form a handle, and downwardly andforwardly to form supporting legs 19a. Also the rear lower side of thehopper is provided with 1 a downwardly and rearwar dly extendingsupporting leg 20. The legs 19aand 20 terminate upwardly from the bottomof the wheels 5.

Though I have shown and described .a particular construction,combination, and arrangement of parts and portions, I'do not wish to belimited to this particular construction, combination, and arrangement,but desire to include in the scope of my invention theconstruction,combination, and arrangement substantiallyas. set forth intheappendedclaims. r
